Objective:To explore the efifcacy and safety for radiofrequency catheter ablation (RFCA) of left bundle branch guided by left bundle potential (LBP), X-ray image with EnSiteNavX System in canine model.
Methods:The RFCA of left bundle branch was conducted in 13 dogs. A mapping catheter was positioned in right atrium to record right-sided His-bundle (R-His) potential, and an ablation catheter via right femoral artery was retrograded to left ventriclefor LBP mapping and ablation. Meanwhile, EnSiteNavX System was used to identify R-His, L-His and LBP at the same time. The potential characteristics in dogs with successful ablation were observed, the PR interval, QRS shape and time limit, AH interval, HV interval, the A/V electro-gram ratio in ablationcatheter at before and after ablation were recorded. The procedural time and X-ray exposure time between LBP with X-ray image method and LBP, X-ray image with EnSiteNavX System method were compared.
Results: There were 9/13 dogs received successful left bundle branch ablation, 3 dogs failed and 1 suffered from complete A-V block. At the successful ablation target site, the LBP-V was (17.8 ± 2.6) ms with the range of (13-21) ms, and the A/V electro-gram ratio<1/10. The procedural time and X-ray expose time were signiifcantly decreased in LBP, X-ray image with EnSiteNavX System method than those in LBP with X-ray image method P=0.007 and P<0.001.
Conclusion:Under the LBP, X-ray image with EnSiteNavX System guidance method, left bundle branch could be safely and effectively ablated to establish left bundle branch block (LBBB) model in experimental canine.

According to the transcriptome dataset of Panax notoginseng, the key geranylgeranyl pyrophosphate synthase gene (GGPPS) in terpenoid backbone biosynthesis was selected to be cloned. Using specific primer pairs combining with RACE (rapid amplification of cDNA ends) technique, the full-length cDNA sequence with 1 203 bp, which containing a 1 035 bp open reading frame, was cloned and named as PnGGPPS. The corresponding full-length DNA sequence contained 2 370 bp, consisted of 1 intron and 2 exons. The deduced protein PnGGPPS contained 344 amino acids and shared more than 73% identity with GGPPS from Ricinus communis and Salvia miltiorrhiza. PnGGPPS also had specific Aspartic acid enrichment regions and other conserved domains, which belonged to the Isoprenoid-Biosyn-C1 superfamily. The quantitative real-time PCR showed that PnGGPPS expressed in different tissues of 1, 2, 3 years old root, stem, leaf and 3 years old flower, and the expression level in 3 years old leaf was significant higher than that in other organs, which suggested that it might not only be involved in the regulation of the growth and development, but also be associated with the biosynthesis of chlorophyll and carotenoids, the development of chloroplast, the shade habit and the quality formation of P. notoginseng.

The PET tracer 5-([11C]methyloxy)-L-tryptophan (5-(11)CMTP) was prepared by nucleophilic fluorination and alkylation reaction via a two-step procedure in order to develop specific tumor probe. The biodistribution and microPET imaging of 5-(11)CMTP were executed. The results unveiled that the overall radiochemical yield with no decay correction was (14.6 ±7.2) %, the radiochemical purity was more than 95% and high uptake and long retention time of 5-(11)CMTP in liver, kidney and blood were observed but low uptake in brain and muscle were found, furthermore, high uptake of 5-(11)CMTP in tumor tissue was observed. It seems that 5-(11)CMTP will be a potential amino acid tracer for tumors imaging with PET.

OBJECTIVETo explore the effect of Yixintai Granule (YG) on mRNA and protein expression levels of AQP2 in renal medulla of chronic heart failure (CHF) rabbits.

METHODSCHF rat model was established by ear marginal vein injection of adriamycin. Successfully modeled rabbits were divided into the model group, the high (8.4 g/kg), middle (4.2 g/kg), and low dose (2.1 g/kg) YG group, and the Furosemide group (2 mg/kg). Besides, a normal control group was set up. Equal volume of physiological saline was administered to rabbits of the model group and the normal control group by gastrogavage. YG at different doses was administered to rabbits of the 3 YG groups by gastrogavage. The intervention lasted for 4 weeks, once per day. After treatment the urine volume and pathomorphological changes of renal medulla tissue were observed. mRNA and its protein expression levels of AQP2 were detected.

RESULTSCompared with the normal control group, the urine volume decreased significantly, mRNA and protein expression levels of renal medulla AQP2 increased significantly in the model group (all P < 0.01). Compared with the model group, the urine volume increased significantly, and mRNA and protein expression levels of renal medulla AQP2 decreased significantly in all medicated groups (all P < 0.01). Compared with the low dose YG group, the urine volume significantly increased and the mRNA expression level of renal medulla AQP2 significantly decreased in the middle and high dose YG groups (all P < 0.01). The expression level of AQP2 protein significantly decreased in the high dose YG group (P < 0.01). Pathological changes of the renal medulla was the most obviously seen in the model group. But they were alleviated to various degrees in all medicated groups. They were more obviously attenuated in the middle and high dose YG groups.

CONCLUSIONYG could improve CHF possibly through down-regulating mRNA and protein expression levels of AQP2 in renal medulla, and elevating the urine volume.

Objective To evaluate the surgical modalities and prognosis in elderly patients with gastric cancer.Methods Sixty three gastric cancer patients aged ≥≥ 75 years underwent radical surgery,with D0 + D1 resection in 32 cases and D2 resection in 31 cases,in Beijing Hospital from January 2005 to December 2009.Results More lymph nodes were dissected in D2 group than those in D0 + D1 group (27.42 ± 12.75 vs.14.59 ± 12.11,t =-4.095,P ＜ 0.05).There was no significant difference in postoperative complication rate [25.81％ (8/31) vs.31.25％ (10/32),x2 =0.095,P ＞ 0.05] and perioperative death rate [3.23％ (1/31) vs.6.25％ (2/32),x2 =0.324,P ＞ 0.05] between two groups.The 5-year survival rate was higher in D2 group than that in D0 ± D1 group (47.3％ vs.21.4％,x2 =6.346,P ＜ 0.05).The 5-year survival rate was higher in POSSUM score (PS) ＜ 20 group than that in PS≥20 group (46.3％ vs.11.1％,x2 =5.492,P ＜0.05).In PS≥20 group,postoperative complication rate did not increase after D2 radical resection(1/8 vs.3/10,x2 =0.824,P ＞ 0.05).Univariate analysis showed that PS ＜ 20 was associated with the prognosis of patients (x2 =5.492,P ＜ 0.05).Cox proportional hazards model showed that lymph node metastasis (OR=4.103,95％ CI:1.790-9.405,P ＜ 0.05) and D2 radical gastrectomy(OR =0.313,95％ CI:0.158-0.620,P ＜ 0.05) were the independent factors associated with the prognosis of patients aged ≥ 75 years with gastric cancer (all P ＜ 0.05).Conclusion Standardized D2 lymph node dissection is beneficial for gastric cancer patients aged ≥75 years.PS ＜ 20,lymph node metastasis and D2 radical gastrectomy are associated with the prognosis of patients.

OBJECTIVETo explore the efficacy differences in early intervention of different acupuncture and moxibustion methods on gastrocnemius fatigue in rats induced by electrical stimulation.

METHODSFifty male SD rats were randomly divided into a control group, a model group, a hand acupuncture group, an electroacupuncture group and a moxibustion group, 10 rats in each group. Electrical stimulation of the sciatic nerve was given in the control group and gastrocnemius fatigue test was induced by electrical stimulation of the sciatic nerve in the model group after anesthesia without other treatment, but just take 6 times interval stimulation in the control group. The hand acupuncture group, the electroacupuncture group and the moxibustion group were treated with the corresponding acupoints stimulation method respectively for 20 min before gastrocnemius fatigue test, and Dazhui (GV 14) and Zusanli (ST 36) were selected. Immediately after gastrocnemius fatigue test, three or four gastrocnemius tissues at the same site on the right side were quickly taken for making specimen for transmission electron microscope (TEM). The changes of skeletal muscle ultrastructure of myofibrils, mitochondria, sarcoplasmic reticulum, glycogen particles were observed under TEM.

RESULTS(1) Muscle fibers disorder, partial mitochondrial vacuolization and glycogen particles smaller were shown in the model group. (2) No abnormalities were shown in the hand acupuncture group and the moxibustion group with mitochondrial morphology and number, which better than that in the model group, and glycogen particles increased. (3) Abnormal changes in morphology were shown in the electroacupuncture group with part of the muscle fibers derangement, Z line malalignment and a few mitochondria vacuolization.

CONCLUSIONHand acupuncture, electroacupuncture and moxibustion have the different effects on ultrastructure of gastrocoemius in rats. Acupuncture and moxibustion have shown good effects on the prevention and treatment of exercise-induced skeletal muscle cell and organelle damage and delaying exercise-induced fatigue.

During the process of electroacupuncture (EA) therapy, whether there being a corrosive effect in ac- upuncture needles was observed. Acupuncture needles were inserted into a rabbit's acupoint to perform a 12-hour electrical stimulation with three types of common EA waveform; additionally two needles were put in 0.9% sodium chloride solution with 12-hour direct current. Afterwards, environmental scanning electron microscope was applied to detect the surface physical characteristics of acupuncture needles. As a result, after a 12-hour continued electri- cal stimulation with three types of common EA waveform in the rabbit, there was no corrosive effect in acupunc- ture needles; but the direct current could cause severe corrosion in acupuncture needles. It is believed that there is no corrosion effect on acupuncture needles in current EA treatment, and some accidents reported in literature may be related to quality of EA device or improper manipulation during the treatment.

OBJECTIVEReport on the intramuscular innervation and vascular supply of the flexor carpi ulnaris (FCU) and the flexor carpi radialis (FCR), the musculo tendon architecture, i.e., the physiological cross-sectional area and fiber length; and explore the possibility of splitting FCU and FCR into 2 parts with individual independent function.

METHODSAnatomic study, angiogram and Sibler's staining technique were carried on human and monkey cadavers. The electric stimulation study was used to reveal independent contraction of each part on monkey FCU and FCR.

RESULTSIt was found that the innervation and blood supply of FCU and FCR come primarily from the proximal neurovascular pedicles. The primary nerve and vascular branch supplying the muscles were divided into 2 subbranches and inserted the proximal quarter of the muscle belly. Then each of the nerve and blood subbranches mn parallel to the central tendon on each side supplying the radial and ulnar compartments of FCU and FCR toward the distal musculotendinous junction. Independence of function of each compartment was confirmed in electrical stimulation studies in primate FCU and FCR. The results of each compartment of the human FCU and FCR architectures were measured and compared with the extensor pollicis longus and the extensor digitorum communis to the index, middle, ring, and small.

CONCLUSIONSBoth FCU and FCR can be split from the distal to the proximal along its tendon into 2 independently functioning neuromuscular compartments. Both radial compartment and ulnar compartment have its own nerve and adequate blood supply. And the study provides useful information for enabling the local transfer of the two muscles as a whole or two separate compartments, both for resurfacing skin soft-tissue defects and for functional tendon transfer.
